Shielded Air Ventilation
Panels Air filter panels, with honeycomb design mounted
in an extruded aluminum edge frame, electronically shields ventilation openings
of equipment enclosures with minimum pressure drop. |

General: |
Shielding
Express Air Vent Panels are
constructed using aluminum honeycomb mounted within a C-channel edge frame. The
panels are supplied ready to mount on the shielded enclosure via a composite
EMI/RFI shielding gasket attached to the panel frame. The panel edge frame has
a mounting hole pattern for either through-bolts or captive insert receptacles.
All panels are made to customer specifications. |
